Color Curves transform and Saved *.cc files

Post by den »

Ref: PWP 8.0.exe 180710.5

"Load color curves" for the Color Curves transform settings is no longer working properly...

The following "PWP8 HSV Test color curves.cc" file was formed and Saved but the V channel did not save properly [it had the control points illustrated]:

ColorCurves 1.0
colorspace 0
npts1 2
style1 spline
point1 0 0 128
point1 1 255 128
npts2 5
style2 spline
point2 0 0 0
point2 1 18 26
point2 2 89 166
point2 3 204 222
point2 4 255 255
npts3 4
style3 spline
point3 0 0 0
point3 1 76 53
end

was Color Curves\Settings\Load color curves... yields:
Screenshot (1)-1.jpg
Screenshot (1)-1.jpg (145.45 KiB) Viewed 1437 times

The H and S channels load properly and the V channel has correct control points but the curve is a horizontal line at vertical = 0 [black].

In the .cc file, npts3 should be 2 and not 4

Did you create this cc file by hand or did PWP create it. If PWP created it, then I need to track down the problem.

PWP8 created the file... ...added edit: There should be 4 points for npts3 but apparently only the first two got Saved. Look closely at the V channel grid, you will see white control points for a spline S-contrast curve except for the one at 255,255.

Fixed for next release. You will need to re-save any incorrect color curves. It was getting the number of control points for the third channel from the first channel.
